Bankart lesion of the shoulder
Bankart lesion : A compression defect on the inferior articular surface of the humeral head due to impingement on the glenoid fossa during recurrent dislocations of the shoulder.
Radiographic Appearance : The Bankart’s lesion is usually seen as a small fracture or a osteophitic deposit probably due to micro fractures, there is often a corresponding Bankart’s fracture of the inferior margin of the glenoid fossa.
The lesion is visible on plain radiographs but a more detailed view can be obtained through multiplanar reconstruction using CT and MRI.
